Change the Kconfig from a "choice" to a conditional block, allowing
multiple FWU metadata storage drivers to be selected simultaneously
instead of being mutually exclusive.
This enables systems with FWU metadata on different storage types
(e.g., both GPT-partitioned block devices and MTD devices) to have
both drivers compiled in. The board can then select the appropriate
driver at runtime based on the devicetree description.
The change converts FWU_MDATA to a menuconfig and replaces the
"choice/endchoice" block with "if FWU_MDATA/endif", making
FWU_MDATA_GPT_BLK default to 'y' for backward compatibility.

There are only a few things found in <mtd.h> today. Go through and audit
the C files which include <mtd.h> and remove it when not required. Then,
add it to the files which had either missed it or had an indirect
inclusion of it.

Sughosh Ganu <[email protected]> says:
The following patch series adds support for version 2 of the FWU
metadata. The version 2 metadata structure is defined in the latest
revision of the FWU specification [1].
The earlier versions of these patches were migrating to a version 2
only support in U-Boot, similar to TF-A. However, based on feedback
from ST [2], this series has been updated to support both versions. A
platform would still be needed to enable one of the two versions of
metadata through a config symbol.
TF-A has code which reads the FWU metadata and boots the platform from
the active partition. TF-A has decided to migrate the FWU code to a
version 2 only support. These changes have been merged in upstream
TF-A.
These changes have been tested on the ST DK2 board, which uses the GPT
based partitioning scheme. Both V1 and V2 metadata versions have been
tested on the DK2 board.
These changes need to be tested on platforms with MTD partitioned
storage devices.

The FWU metadata access driver for MTD partitioned devices currently
uses a statically allocated array for storing the updatable image
information. This array depends on the number of banks and images per
bank. With migration of the FWU metadata to version 2, these
parameters are now obtained at runtime from the metadata.
Make changes to the FWU metadata access driver for MTD devices to
allocate memory for the image information dynamically in the driver's
probe function, after having obtained the number of banks and images
per bank by reading the metadata. Move the image information as part
of the driver's private structure, instead of using a global variable.

In version 2 of the metadata structure, the size of the structure
cannot be determined statically at build time. The structure is now
broken into the top level structure which contains a field indicating
the total size of the structure.
Add a size parameter to the metadata access API functions to indicate
the number of bytes to be accessed. This is then used to either read
the entire structure, or only the top level structure.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

In the FWU Multi Bank Update feature, the information about the
updatable images is stored as part of the metadata, on a separate
region. Add a driver for reading from and writing to the metadata
when the updatable images and the metadata are stored on a raw
MTD region.
The code is divided into core under drivers/fwu-mdata/ and some helper
functions clubbed together under lib/fwu_updates/

The common code can now read, verify and fix meta-data copies
while exposing one consistent structure to users.
Only the .read_mdata() and .write_mdata() callbacks of fwu_mdata_ops
are needed. Get rid of .get_mdata() .update_mdata() .get_mdata_part_num()
.read_mdata_partition() and .write_mdata_partition() and also the
corresponding wrapper functions.

Instead of each i/f having to implement their own meta-data verification
and storage, move the logic in common code. This simplifies the i/f code
much simpler and compact.

In the FWU Multi Bank Update feature, the information about the
updatable images is stored as part of the metadata, which is stored on
a dedicated partition. Add the metadata structure, and a driver model
uclass which provides functions to access the metadata. These are
generic API's, and implementations can be added based on parameters
like how the metadata partition is accessed and what type of storage
device houses the metadata.
